I bought a 1999 Z28 back in 2004 with an automatic transmission. It only had 10,000 miles on it. Once it got to 12,000 or 13,000 The transmission wore out. So I bought a TCI automatic transmission. That lasted only about 2,000 - 3,000 miles. So I had the TCI rebuilt. That lasted about the same. They guy that has been working on the car says it wears out the same. He says he thinks it is the computer not telling it to have enough pressure. What do you think.
